The thing USC coach Lane Kiffin probably gets criticized for the most after games is his playcalling. But Kiffin said Wednesday he believes his dual role helps develop a closer relationship with skill players, especially quarterback Matt Barkley.

"Sure, I've thought about (not calling plays)," Kiffin said. "You better look at everything you are doing with your program. At the end of the day, I feel it is too valuable, the relationship that playcalling helps develop with our skill players.

"I go back to having the conversation with Coach (Pete) Carroll when I took the Raiders job. He said the worst thing I can do is to give all that up, because the players feel that from you. That's always kind of sat in the back of my head when I've thought about it."

Kiffin said his dual role might have played a part in Barkley's decision to return for his senior season.

Shaw practices at safety

Although Josh Shaw worked at cornerback Tuesday, he spent Wednesday's practice at safety because starter Jawanza Starling did not practice. Assistant coach Marvin Sanders expressed confidence in starter Torin Harris, who has struggled this season.

"I have confidence in Torin," Sanders said. "I think it's important what we have there (instead of adding players)."

Shaw said he looks forward to playing cornerback, which requires more individual work.

"I just need to do more with my feet and hands, for jamming the receivers," Shaw said. "You're out there on an island at cornerback."

Kiffin said he has not decided whether to play Shaw at cornerback against Washington.

Wishful thinking

Sanders said he would love to have wide receiver Marqise Lee at cornerback but knows it is unlikely to happen.

"Any coach would be crazy not to want him," Sanders said. "If (Kiffin) wants to offer him up, I'll take him."

Sanders said Lee would not require a transition period to play defense.

"No, not with that kid, you just need to see him running and you can tell what kind of athlete he is," Sanders said.

Heidari regroups

Kicker Andre Heidari missed two field goals in a game for the first time in his career last week against Utah.
